initcmd

var InitCmd = &cobra.Command{
	Use:     "init [flags] [USERNAME] [DIRECTORY]",
	GroupID: cmd.GROUP_SUBSYSTEMS,
	Short:   "Initialise a Geneos installation",
	Long: strings.ReplaceAll(`
Initialise a Geneos installation by creating the directory
structure and user configuration file, with the optional username and directory.

- |USERNAME| refers to the Linux username under which the |geneos| utility
  and all Geneos component instances will be run.
- |DIRECTORY| refers to the base / home directory under which all Geneos
  binaries, instances and working directories will be hosted.
  When specified in the |geneos init| command, DIRECTORY:
  - Must be defined as an absolute path.
    This syntax is used to distinguish it from USERNAME which is an
    optional parameter.
	If undefined, |${HOME}/geneos| will be used, or |${HOME}| in case
	the last component of |${HOME}| is equal to |geneos|.
  - Must have a parent directory that is writeable by the user running 
    the |geneos init| command or by the specified USERNAME.
  - Must be a non-existing directory or an empty directory (except for
	the "dot" files).
	**Note**:  In case DIRECTORY is an existing directory, you can use option
	|-F| to force the use of this directory.

The generic command syntax is as follows.
| geneos init [flags] [USERNAME] [DIRECTORY] |

When run with superuser privileges a USERNAME must be supplied and
only the configuration file for that user is created.
| sudo geneos init geneos /opt/itrs |

**Note**:
- The geneos directory hierarchy / structure / layout is defined at
  [Directory Layout](https://github.com/ITRS-Group/cordial/tree/main/tools/geneos#directory-layout).
